Alexis Bledel, Vincent Kartheiser are parents -- um, for a while now, actually

Gilmore Girls and Mad Men have spawned. In other words, Alexis Bledel and Vincent Kartheiser had a baby. And turns out the little Mad-Gilmore babe (okay, let's keep brainstorming nicknames here) has actually been around for a while. The pair's son was born last fall, reports Us Weekly. So, these two are officially the winners of stealth-parenting At least six months under the radar.

Reportedly, Luke (Scott Patterson) was the one who hinted at the news when he called Alexis "a proud new mother." A proud new mother who devises a genius plan to hold of the media from inevitably writing trendy headlines about her newborn. Total Rory move.
